I got the idea for the following script from a site I recently visited. When I left, a cute little window popped up, thanking me for visiting their site, and urging me to come back real soon. The window actually made an impact on me, surprisingly. Here is a script that does just that- pops up a small, toolbarless window as the surfer leaves the page. To avoid over-irritating your surfers, the script comes with the added feature of only popping up the first time the surfer enters and leaves the page.
